Well, Sorry for necroing this, but I have the same problem. My main computer running obs is windows and my other is running ubuntu 14.04, I've mapped a network drive (Y:\) then selected the file that way. It doesn't update the preview. However, if i open the text source and click Ok it will update the text. I use samba for the file share.
I looked through my logs, but there wasn't anything about this issue.
I guess I could do a FTP every 10 seconds, but that also seems a bit stupid to have to pull the file like that.
Any help in this matter would be awesome!
Thanks in advance
